抽水蓄能作用明显,可利用低谷电能抽水,以供峰荷时再发电或需要时供水。电网中当时无法充分利用的低谷电能通过储存转换,变废为宝,以丰补歉、循环更新使用,使系统中各种火电等机组可在较优工况下平稳运行,对节能减排、保护环境十分有利。水利水电、火电核电、风能太阳能等蓄能运行均有利于可持续发展。

Piezostack-based active mounts have shown great efficiency for vibration control in a wide frequency range. In this paper, we investigate the performances of the global semi-active control strategy presented by Ichchou et al. [ ] for a control system consisting of an active mount and a supported mass. The control strategy allows extracting vibrations energy of the supported mass, storing it in accumulators to be reused for powering in part the actuators (two piezostacks). Consequently, energy needs are reduced versus good control performances comparable to those of the active control based on the negative velocity feedback. The performances of the controller are evaluated in both frequency (transmitted force) and time (acceleration) domains which show that vibrations of the supported mass due to base excitations are efficiently attenuated with the proposed law. An energetic analysis confirms the reduced energy requirement compared to the active scheme.

Effect of the new maternity insurance scheme on medical expenditures for caesarean delivery in Wuxi,

Aiming to control rising medical expenditures and help improve China’s healthcare systems, this study examined whether a cap-based medical insurance scheme with shared financial interest between the insurance and healthcare providers is effective in containing hospitals’ C-section medical expenditures. We used 6547 caesarean delivery case records from a teaching tertiary-level general public hospital located in Wuxi, China (2004–2013), and used the Chow test to investigate the possibility of significant variation in mean medical expenditures for caesarean deliveries pre- and post-reform. We also used paired sample t-tests and linear regression models to compare the mean medical expenditures between insured and uninsured women undergoing caesarean delivery during the post-reform period. After the scheme’s implementation, medical expenditures for caesarean deliveries declined and the medical expenditures of women covered by the scheme were significantly lower than those of uninsured patients. These findings indicated the scheme’s effectiveness in minimizing caesarean delivery expenditures. The cap-based medical insurance scheme with shared financial interest between insurance and healthcare providers would likely steer healthcare providers’ behaviors in a more cost-effective direction.
